The reaction between
KMnO4 and
MnSO4 in a neutral medium involves the redox process where potassium permanganate acts as an oxidizing agent. In neutral or slightly alkaline solutions, permanganate
(MnO4−)is typically reduced to manganese dioxide (
MnO2 ). The typical reduction of permanganate in a neutral medium can be represented by the equation:
MnO4−+2H2O+3e−⟶MnO2+4OH−
Simultaneously, manganese(II) sulfate
(MnSO4) can be oxidized to manganese dioxide
(MnO2), showing that manganese ion
(Mn2+) in
MnSO4 is oxidized by
KMnO4 to
Mn4+ in the form of manganese dioxide. This type of reaction commonly takes place in solution as both compounds are water-soluble and can interact directly when dissolved.
Therefore, the correct answer to the question is:
Option C:
MnO2.
